CASE STUDY
Blocking Uploads to Non-Corporate Websites
The blind spot costing Australian organisations millions.
Every day, staff upload files to websites that your security team never approved. Personal Dropbox accounts. WeTransfer links. ChatGPT prompts containing customer data. Most organisations only discover this happened after the damage is done, if they discover it at all.
Traditional security tools watch the network perimeter. They block known threats coming in. But they have no visibility over what leaves through the browser, through cloud apps, through the dozens of unsanctioned tools employees use to “get work done faster.”
This is shadow IT exfiltration. It accounts for a significant proportion of data breaches and it happens without malicious intent. An employee uploads a spreadsheet to a personal cloud folder so they can work from home. A contractor pastes source code into an AI assistant. A sales rep emails a pricing sheet to their personal Gmail “for safekeeping.”
The common thread: sensitive data left the building, and nobody knew.
How GuardWare addresses it.
GuardWare INSIGHT monitors data movement across endpoints in real time. It watches what users do with files, including uploads to non-corporate websites, cloud storage platforms, AI tools, and personal email services. INSIGHT can also white-list and black-list websites.
When a user attempts to upload sensitive content to an unauthorised destination, INSIGHT can alert, log, or block the action depending on your policy settings. Security teams see exactly what was attempted, by whom, and when.
Critically, INSIGHT works alongside GuardWare DISCOVER. DISCOVER identifies and classifies your sensitive data first, so INSIGHT knows which files matter most. Without classification, you’re monitoring noise. With it, you’re protecting what actually needs protection.
For the most sensitive content, GuardWare PROTECT adds a final layer of defence. Files encrypted with PROTECT remain secured even if they are uploaded to an unauthorised destination. Data that reaches a personal cloud account or AI tool is useless without the encryption keys, keys the recipient doesn’t have. If monitoring fails to prevent an upload, encryption ensures the data cannot be exploited.
The Outcome
Organisations gain visibility over data leaving through channels they previously couldn’t see. Policy violations get flagged before they become breaches. And if sensitive data does slip through, persistent encryption renders it worthless in the wrong hands.
Shadow IT stops being a blind spot. It becomes a managed risk.
